This was likely made before those red and white tags became designated for PSMH, there are 150 watt MH lamps but that's as low as it goes to my knowledge before they become PSMH.
Maybe the red and white tags are only for the new E-Act campliant PMH fixtures (175-450w PMH had to be more efficient). Because I've seen new MH fixtures in NH that weren't there when i went last year and they were plain red tags. The red and white tags look so odd to me.
